Seoul vs. Surabaya: Detailed 2026 Cost of Living & Quality Comparison

Seoul and Surabaya represent vastly different urban environments, from South Korea's bustling metropolis to Indonesia's vibrant port city. Seoul, with a population of approximately 6.5 million, stands as one of the world's leading global cities, renowned for its technological innovation, cultural influence, and high standard of living. In contrast, Surabaya, Indonesia's second-largest city with a population of around 6.5 million, serves as the country's economic hub but operates on a much different scale. This comparison examines key quality of life and cost of living metrics to provide insights into the distinct characteristics of these two dynamic cities.

Overall Quality Comparison

Seoul consistently outperforms Surabaya across nearly all quality-of-life metrics. The city's Quality of Life Index stands at 104.89, significantly higher than Seoul's 86.3 (derived from indices like safety, healthcare, and climate). Seoul also boasts a higher Purchasing Power Index (70.2) compared to Surabaya's 30.84, reflecting the greater economic purchasing power enjoyed by residents in South Korea. While Surabaya's GDP per capita ($13,900) is considerably lower than Seoul's ($59,300), this gap is mirrored in the cost of living, with Seoul's higher salaries helping offset many expenses despite the elevated cost of living overall.

Cost of Living Comparison

The cost of living disparity between these two cities is stark. Seoul's overall Cost of Living Index is 59.3, nearly double Surabaya's 27.15, reflecting the significant price differences across most categories. Basic groceries are substantially cheaper in Surabaya, with items like white rice costing just $0.89/month versus $4.50/month in Seoul. Transportation costs also favor Surabaya, with public transit fares averaging $0.41 per ride compared to Seoul's $1.50. Even dining out remains more affordable in Surabaya, where a mid-range restaurant meal for two costs approximately $6.50/month versus $45.00/month in Seoul. However, certain categories show closer alignment, such as childcare expenses, where monthly kindergarten fees are comparable between the two cities.

Property Comparison

The property markets in these cities reflect their broader economic differences. While Seoul's property price-to-income ratio is 28.7, similar to Surabaya's 28.7, the absolute costs in Seoul remain substantially higher. A 85m² apartment in Seoul's city center averages $1,000/month, nearly seven times more expensive than Surabaya's $146/month. For those considering long-term investments, Seoul's 3.5% mortgage interest rate is significantly lower than Surabaya's 7.5%, making homeownership more financially accessible in the South Korean capital despite the higher purchase prices.

Income Comparison

The income disparity between these cities is substantial, with Seoul's average monthly net salary of $3,500 being nearly 12 times higher than Surabaya's $299. This significant income gap helps explain the higher cost of living in Seoul, as residents generally have greater purchasing power to offset many expenses. However, this also means that opportunities for career advancement and higher earning potential are substantially more prevalent in Seoul. In conclusion, Seoul and Surabaya offer fundamentally different lifestyles and economic experiences. Seoul provides a world-class quality of life with superior infrastructure, services, and amenities, though at a significantly higher cost. Surabaya offers a more affordable alternative with lower living expenses, though with some trade-offs in terms of infrastructure quality and safety. The choice between these cities ultimately depends on individual priorities regarding quality of life, career opportunities, and budget constraints.
